It used open source data on the deaths of 3,000 mobilized troops over the past year.

More than half of the dead draftees were between the ages of 30 and 45, the report said.

Mobilized Russian troops who died in Ukraine were, on average, killed just four and a half months after their deployment, per a new investigative report.

Using open source data on the deaths of about 3,000 mobilized troops, independent Russian outlets Important Stories and the Conflict Intelligence Team calculated an estimated "life expectancy in war" for those called up to fight.

They noted in a Thursday report that the actual number of Russian casualties could be far higher. The outlets said they compiled their list with help from newspaper announcements or messages from officials and relatives.

At least 130 mobilized troops died in their first month of mobilization, and 20% of the 3,000 deaths assessed occurred within the second month of deployment, per the outlets.
